Abstract

The invention discloses an amphibious aircraft buoy detection device and a detection method thereof, and relates to the technical field of aircraft buoy detection devices. The buoyancy of the airplane buoy at the corresponding draft depth can be conveniently detected. The device comprises a water tank and a downward pressing mechanism, a hydraulic cylinder is installed on one side of the water tank through a supporting frame, and the downward pressing mechanism comprises a first fixing frame and an arc-shaped pressing plate. The method comprises the following steps: pouring water into a water tank, and placing an aircraft buoy to be tested in the water tank. By arranging an air bag, a conducting ring, conducting strips and other structures, the adjusting frame can be driven to move downwards while an arc-shaped pressing plate is pressed downwards, the air bag supports a sliding rod to keep in situ based on buoyancy, when the arc-shaped pressing plate is pressed downwards by a certain distance, the conducting ring makes contact with and conducts a circuit between the two conducting strips, and a control assembly receives an electric signal, so the reading of the display screen is locked; by means of the mode, the buoyancy of the airplane buoy at the corresponding draft depth can be effectively obtained.

Description

technical field [0001] The invention relates to the technical field of aircraft buoy detection devices, in particular to an amphibious aircraft buoy detection device and a detection method thereof. Background technique [0002] An amphibious aircraft refers to an aircraft that can take off, land and park on the water, and can adapt to two different environments on the water and in the air; the aircraft pontoon is one of the core components to ensure that the amphibious aircraft can land on the water surface, in the production and processing of aircraft pontoons , in order to ensure the reliability of the aircraft buoy in use, it is often necessary to carry out a series of tests, the most important of which is the test of the bearing capacity of the aircraft buoy; although the current aircraft buoy detection device can meet certain detection requirements, it is inconvenient to use and It is impossible to reliably measure the buoyancy corresponding to the draft according to th...
